VENDING APPARATUS.

I SPECIFICATION forming part of Letters Patent No. 430,465, dated June 1'7, 1890.

Application filed February 20, 1890. Serial No. 341,133. (No model.) 7

To (0% whom it Hwy concern.-

Be it known that I, JAooB J. BUsENBENZ, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Vending Apparatus, of which the following is a specification.

My invention relates to an improvement in the class of vending apparatus arranged for the insertion of a coin representing the price of the article or matter to be purchased, and which serves to render operative the delivery mechanism. I have particularly designed my present improvement for the vending of drinkingwater (as mineral water) or other beverage commonly sold by the glass, though the principle of its construction and manner of operation may be employed for the vending of other matter. Hence I do not wish to bounderstood as limiting my invention to the details hereinafter described, adapting it especially to the first-named purpose.

The accompanying drawing shows my improved apparatus as adapted for the sale and delivery of mineral water by the glassful by a broken view in sectional side elevation.

A is a chamber, which should be provided with a removable cover 7" and with a coin-receptacle 13, supported below its base q. A tube C extends from the front side of the chamber, at which it may be supported, as shown, and carries on its upper side a receptacle D, which should be of a size adapting it to contain the amount of liquid intended to be sold for the denomination of coin for which the apparatus is designed. The base of the receptacle D, where it is joined to the tube C, should be open and fianged,as shown, and it communicates with the. tube through an opening 0. From the upper closed end of the receptacle leads a vent-pipe 13. Inside the tube Cis a sliding valve E, provided with two openings 0) and r, and normally held by a confined spring or when distended, as. shown, with its opening o coincident with the opening 0, and in that position producing communication of the receptacle D with the interior of the chamber A through an opening m in the tube 0. In the base of the tube is an opening Z, through which to permit the coin.

to drop, means in the form of a guide-tube Z being provided, if desired, to direct it into the coin-receptacle b. The coin-outlet openingl is normally covered by a hollow piston C, fitting within the tube C, with its forward or inner end, which maybe closed, as shown, abutting against the adjacent end of the valve E, and its opposite end, which is open, reaching to or nearly to the lower end of a chute F, extending from a horizontal slot 5' in the front side of the chamber A. A plunger-rod t' extends through the front wall of the chamber into the tube C, being reduced in diameter, as shown, toward its inner end, where it projects through a diaphragm near the mouth of the chute, and between which and a stop as on the plunger-rod is confined a spring 7; for controlling the rod. Coincident with the inlet-opening 0 in the upper side of the tube C is an outlet-opening o in its base, from which leads a discharge-pipe h to a nozzle g or the like, extending from the outer side of the chamber.

In'the device as illustrated the chamber A forms a' reservoir for the liquid to be sold and delivered, the delivery being to the extentof a glassful at a time and produced in the following manner by inserting a coin G (as a penny) into the slot .9: The chute F guides the coin into the tube C, which it enters be tween the diaphragm ac and open end of the hollow piston C, forming a cover for the latter, and thus an obstruction or bearing for the plunger-rod t',whieh,if pushed inward with no coin in the position described, would obviously merely enter the hollow piston without producing any further result. IVith the coin in such position, however, when the rod 1' is pushed inward it forces the hollow piston ahead of it until the coin reaches its outletopening Z, through which it drops when freed by the return, by the resilience of the spring 7;, of the plunger-rod when released. The forward or inward movement of the hollow piston C forces ahead of it the valve E, moving its opening 1: out of coincidence with the opening 0 and closing communication with the latter of the reservoir A, but bringing the opening o into coincidence with the open- IOC ings 0 and 0, and permitting the contents of the receptacle D, previously filled from the reservoir through the openings m, o, and 0, to discharge through the pipe hinto a drinkingvessel II, which should be suitably supported, as shown, to receive the discharge.

On releasing the plunger-rod (whereby the com is also released and permitted to drop, as stated) the springs n and 70 return the parts 1n the tube 0 to their normal positions, 1n which the valve E permits refilling of the receptacle D to take place to prepare the apparatus for another discharge on inserting a suitable coin G.

The gist of my improvement lies in the hollow piston in the tube 0, having its open end normally at or near the mouth of the chute to permit the inserted coin to render the plunger-rod operative for the purpose of moving the hollow piston to actuate suitable dellvery mechanism. Hence I do not Wish to be understood as limiting my invention, in its broadest sense, to any particular form of the delivery mechanism, that illustrated and described serving to show one form thereof for a particular purpose.

What I claim as new, and desire to secure I by Letters Patent, is

1. In a coin-operated vending apparatus, the combination, with a chamber for containing the article to be delivered and delivery mechanism substantially as described, of a tube 0, supported in the chamber, a chute F,

leading trom a slot 8 into the tube, a hollow plston C ,open at one end normally near the mouth of the chute, and a spring-controlled plunger-rod 2', extending into the tube, substantially as and for the purpose set forth.

2. In a coin-operated vending apparatus, the combination of a reservoir A, containing a chute F, leading from a slot 3, a receptacle D ,provided with a discharge-pipe, a confined sllding valve E, having an opening 1:, normally affording communication between the said. receptacle and reservoir, and an opening o',nor1nally closed by the position of the valve, and means, substantially as described, for controlling the valve B, substantially as and for the purpose set forth.

3. In a coin-operated vending apparatus, the combination, with a chamber A, forming the reservoir, of a tube 0, supported in the chamber and communicating therewith, a chute F, leading from a slot 8 into the tube, a receptacle D,communicating with the tube through an opening 0, a coin-outlet opening Z and a discharge-opening o in the tube, the latter coinciding with the opening 0, a springcontrolled valve E inside the tube 0 and provided with openings Q) and o, a hollow piston 0', open at one end and confined in the said tube with its open end normally adjacent to the mouth of the chute, and a plunger-rod 1', extending into the tube, substantially as and for the purpose set forth.

4. A coin operated vending apparatus comprising, in combination, a chamber A, forming a reservoir, a tube 0, supported in the reservoir and communicating therewith through an opening m, a chute F, leading from a slot 8 into the tube, a receptacle D, having a ventpipe extending from its upper end and supported at its open base on the tube C, over an opening 0 therein, a discharge-pipe h, leading from an opening 0 in the tube, and a coinguide l, leading from an opening Z therein, a valve E inside the tube, provided with openings o and v, aspring n, normally maintaining the opening 0 coincident with the spring 0, a hollow plunger 0, abutting at one end against the valve E and normally extending at its opposite open end near the mouth of the chute, and a spring plunger-rod t', extending into the tube, the whole being constructed and arranged to operate substantially as and for the purpose set forth.
